ENvEL'or.

To all whom it may concern: Be it known that I, BENJAMINJOAQHIM, acitizen of the United States, residing at Newark, in the county of Essexand State of N 7 Jersey, have invented certain new and usefulImprovements in Envolo s; and I do hereby be a full, clear, and exactdescription of the invention, such'as will enable others skilled in theart to which it appertains to make and use the same, refer enee beinghad to the accompanying drawings, and to' figures of reference markedthereon, which form a part of this specification. 7 J

This invention relates to an envelop which is of a form that requires ablankwhich is square, and therefore is out without waste of material.

The invention also provides an envelop which can be sealed, but which,also permits the sealing flap to be tucked into a fold so thattheenvelop can be fastened in a way to permit its being sent through themail other than first class.

The invention is illustrated in the accompanying drawing, 1n which-Figure 1 1s a view of a blank. Fig. 2 1s a perspective view of the blankat its first fold ing, and Fig. 8 is a similar viewwith the folding morecomplete d. Fig. 4 is a perspective View showing the scaling flapentering the fold where it is placed when not sealed. Fig. 5 is a blankwith securing slots therein, and Fig. 6 illustrates the function of theslots.

The envelop is formed from a blank 10 which is square and can be easilyand eco-' nomieally cut. The blank is scored or suitably marked as tothe folding places at four parallel linesin one direction, and twopara-L .lel lines in a direction at right angles to the first mentionedlines.

In the drawing the scored lines 11, 12, 13

and 14 are shown horizontally, and the vertieal lines are at 15 and 16.These lines form a central panel 17, an upper panel 18 and a lower panel19, these panels being in 'uxtaposition. The panels are in a row anextend in a directionleading from one corner of the blank to the cornerdiagonally across. Between the upper folding line 11 andone point of theblank is formed the sealing fia 20, and the opposite end of the line '14an the point of the blank form the end lie .21. Flanking the centralpanel are the si e flaps 22 and 213, and flanking the upper and lowerpanels are the wings is; as in Fig.

as in Fig. 4.

I Application "filed December 21, 1908. Serial No..468,421.

1. The bottom panel 19 is folded first, as in Fig. 2, and the end flaps22 and 23 are folded over across the central and lower panels, at thesame time inclosingthe lower wings 24.

Then the envelop appears as in Fig. 3, and

when the parts so folded are swung together, the sealing flap 20 can bestuck to the outside of the central panel 17. ll desired, however, thescaling flap can be slid in between'the panel 17 and the folded side fias The blank can be cut with t ie slots 25 in one side flap and sodisposed v that they are in a position to receive the point 26 of theopposite side flap, when the envelop is folded as in Fig. 6.

The envelop can be used for carrying articles to a destination, or theblank itself can be printed on one side with advertisingmatter, or anydesired use can be made of the same. When the envelop is to be used forcarrying articles or papers of value, security the locking of the sideflaps shown in Fi' 6.

The central, upper and lower panelsare o the same or nearly the samedimensions, and this is the preferred comparative sizes of the o positeelements of the other parts of the b ank;

Having thus described my invention, what I claim is 1. An envelop formedfrom a square blank having a central panel, upper panel and lower panelof the same dimensions, fla s on the ends of the upper panel andthe owerpanel, side flaps flanking thecentral panel, and wings connecting theside flaps, the upper panel and the lower panel.

2. vAn envelop formed from a square blankhaving a central panel, upperpanel and lower panel of the same dimensions, fia s on the ends of theupper panel and the ower panel, side flaps flanking the central panel,and wings connecting the side fia s, the upper panel and-the lowerpanel, tie side flaps having co-acting means to lock the side flaps whenthese flaps are folded across each other.

- 3. An envelop formed of a square blank having a central panel, upperpanel and lower panel in a row and extending in a direction leading fromone corner of the blank to the corner diagonally across, flaps on theouter edges of the upper and lower panels,

side flaps flanking the, central panel, and

. wings connecting the side flaps with the upper panel and the lewerpanel.
